PATENT GATE-LATCH.

SPECIFICATION forming part of Letters Patent No. 295,753, dated March 25, 1884.

Application filed January 14, 1884. (No model.)

i To all whom, it may concern:

Be it known that I, JOHN B. HAsENoHR, of

Terre Haute, in the county of Vigo and State of Indiana, haveinvented certain new and useful Improvements in Gate-Fastening Devices;

and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which formpart of this specidetails of construction and combination of parts as will be hereinafter distinctly pointed out. l

The device may be used as a latch for both sliding and swinging gates or doors, in which first instance the latch employed on the gate for maintaining the same in a lockedposition would be fixed or stationary, while in the second case the latch would be a movable or slidspearshaped end, which enters between and is retained by the spring-bolts. Fig. 3 is a view in detail, showing the manner of movable:

connection of the end of the levers with the shank of the sliding bolts, by which an increased range of movement of said bolts is permitted.

Reference being had to the several parts by letter, A represents a metal plate provided with screw-holes, by which it may be secured to the gate-post or door-frame. Secured to this plate by rivets or otherwise are twosmaller 1 plates, a, which have formed on or attached to them in any suitable manner a hollow shell or cy1inder,'B. Within each shell, and mov-- ing through the heads thereof, is a sliding.

bolt, 0, terminating in a shank or prolongation, 0, which projects outwardbeyond the outer endof said shells.

Surrounding the smaller portion of the bolts within the shells, and bearing between the outer ends thereof and the enlarged portion of the bolts, is a helical spring, D, which springs are compressed, when the bolts 0 are forced apart, bythe action of the latch passing between them, and again expanded of their own resiliency, thus forcing the bolts outward to engage behind the latch.

d represents the latch, the manner in which it is engaged by the bolts being shown in dotted lines.

To the end of the shank of the lower bolt, or it may be on the end of the upper one, is a small knob, by which the said bolts aredrawn apart when it is desired to release the latch from its fastening. In the performance of this act or operation both bolts are operated simultaneously through the medium of suitable mechanism connecting theni at or near their outer ends. This means of connection consists of compound lever mechanism, which I will now proceed to describe, viz: Turning on a pivot, e, at the lower left-hand corner of the plate Ais a lever, E, whose free end is formed rounded or circularly, as shown, which works in an opening or slot made through the shank or smaller portion 0 of the bolt. (See Fig. 3for plane faces or edges of the fuller illustration.) This lever E, with respect to the other parts of the connecting mechan-- ism, constitutes a lever of the second class, its fulcrum being at e, and the point of resistance being at f, where itis pivotedto thelower end of a rod, F,which rod transmits the power applied at the knob to the lever above, which operates the upper bolt. Pivoted between lugs B, formed with the upper shell, B, is a second lever, E, this being one of the first class, its pivotal point being its fulcrum, and. that end to which the upper end of rod F is pivoted being the point at which the power acts to draw in the upper bolt.

In the above means of connection it will be observed that by taking hold of the knob on the end of the lower bolt and pulling down, both bolts-will be simultaneously drawn in,

and that when the knob is released the resili- I 5 device would sometimes prove inoperative.

In my case these ends are permitted to move inward and outward in the slots as the bolts are operated, thus permitting suflicient movement for a full and free operation of parts.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The shells provided with the inwardlyclosing bolts, and the springs located in said 2 5 shells, for actuating the bolts toward eachother, in combination with the levers E E and rod F, connecting the outer ends of said bolts, sub- I stantially as described.

2. The upper and lower shells having the 0 springs. and bolts located and working therein,

as described, the upper shell having lugs B, in combination with lever E, rod F, and the lever E, fulcrumed at said lugs, all connected substantially as and in the manner described.

3. The upper and lower shells having the springs and the bolts located therein, and formed with the slotted shanks, as described, said upper shell having the lugs B, in combination with the levers E E, having one of their ends rounded and extending through the slots in the bolt-shanks, and the rod F, connecting said levers, substantially as shown and set forth.

4. The plate A, having screw-holes, and the plates a secured thereto, the shells B, attached to said plates at, and formed substantially as shown, the springs and the bolts working in said shells, the lower one of whichis provided with the knob, in combination with thelevers E E, pivoted and connected with the boltshanks, as described, the rod connecting said levers, and the spear-shaped latch, all substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereunto affix my signature in presence i of two witnesses.
